How to Fix “Site Is Using Outdated Security Settings” on Server

Flavio Martins

Recent efforts by browsers urge administrators to update SSL security on websites. This includes a big push to upgrade legacy SHA-1 certificates to SHA-256. Staying up-to-date is critical for ongoing data security issues and keeping online trust.

The Chrome browser led the way in how browsers are choosing to handle SHA-1 Certificates, and customers and users on some sites secured by DigiCert have reported that they are getting an error that reads, “This site is using outdated security settings that may prevent future versions of Chrome from being able to safely access it."

The problem is related to a locally installed legacy intermediate certificate that is no longer used or required for the certificate installation. The problem can affect any client platform with a locally cached or installed intermediate certificate.

Legacy Intermediate Certificate

The certificate in question is the “DigiCert High Assurance EV Root CA” certificate. This temporary intermediate certificate was used in years past as part of a compatibility chain for older devices. This certificate is unnecessary for installations.


The certificate chain for this website contains at least one certificate that was signed using a deprecated signature algorithm based on SHA-1.

One of the reasons this error will appear is if there is a cross-signed SHA-1 intermediate certificate in your certificate chain.

Is the Error on the Server or Browser Side?

To determine where the error is occurring, use DigiCert SSL Installation Diagnostic Tool. Type in the name of your server and click “Check Server.” If a cross-signed intermediate certificate shows up in the certificate chain then the problem is on the server side. If there is no intermediate certificate in the chain, then the problem is on the browser side. To fix the error on the browser, side click here.
